Electrical Tracking Formation on Silane Epoxy Resin under Various Contaminants
Abstract: Contamination at the
surface of the insulator becomes a serious problem. Especially for the tropical
area, humidity and rainfall play an important role in wetness by the water at
the insulator surface, which result in the presence of contaminant and leakage
current flowing at the surface. This leakage current will generate heat which
occurs at the surface of an insulator. This ultimately leads to flashover. This
paper presents the influence of contaminants to leakage current and formation
of electrical tracking at the surface of epoxy resin compound wit silicon
rubber. The test was based on IPT method with NH4Cl as contaminants. The
industrial and coastal contaminants are used to explain the effect of
contaminant at surface tracking process. The flow rate of contaminant was 0.3
ml/min. The 3.5 kV AC high voltage 50 Hz was applied to the top electrodes. It
is found that industrial contamination resulting in the smallest surface
leakage current is 327.6 mA. Also it is found that coastal contaminant showed
the severest damage at surface of test sample. Therefore, special treatment of
the sample is needed under these conditions so that the material performance
can be improved, especially against the electrical tracking.
